Cov Kev Ceev Faj Thiab Cov Kev Cai Rau Kev Ua Pob Zeb Uas Tiv Thaiv Hluav Taws Hauv Lub Qhov Cub Hloov Pauv

Lub tshuab cua sov qhuav hom tshiab no feem ntau yog siv rau kev xaiv cov khoom siv refractory, feem ntau yog silicon thiab txhuas refractory cov ntaub ntawv, cov khoom siv refractory kub siab-alkaline, cov khoom siv refractory tsis sib xws, cov khoom ua ntej, cov khoom siv rwb thaiv tsev refractory. Ntawm lawv, nws feem ntau yog cov cib refractory. Lub tshuab cua sov feem ntau muaj cov cib alumina siab, silicon mullite cib, magnesium txhuas spinel cib, magnesium chromium cib, pob zeb dawb huab cib, thiab lwm yam. Cov cib refractory no yuav tsum tau them sai sai rau cov teeb meem thiab cov kev cai hauv qab no thaum ua masonry.

01Cov khoom xyaw cement, qhov loj ntawm cov khoom me me thiab qhov sib piv ntawm cov cib uas siv ua cib yuav tsum ua tau raws li qhov yuav tsum tau ua. Cov cement yuav tsum tau do thiab siv rau hauv ob teev.

02Thaum kawg, tus naj npawb ntawm cov cib yuav tsum tsis pub tsawg dua ob kab, thiab qhov tuab ntawm cov cib yuav tsum tsis pub tsawg dua 3/4 ntawm qhov loj thawj. Yog tias qhov sib txawv yog 1.5 npaug ntawm qhov tuab ntawm cov cib tsim, ib kab yuav tsum raug tshem tawm kom hloov cov cib peb kab. Lub ntsiab lus

03Hauv thaj chaw ua cib, cov cib refractory uas ua los ntawm txhua kab yuav tsum yog tib theem (tuab thiab kam rau siab).

04Tom qab ua lub cib uas tiv taus hluav taws lawm, txoj kab sib dhos ntawm lub cib ntsug yuav tsum sib luag rau txoj kab nruab nrab ntawm lub qhov cub, thiab txoj kab sib dhos ntawm lub nplhaib yuav tsum sib dhos rau txoj kab nruab nrab ntawm lub qhov cub.

05Cov vuas uas tiv taus hluav taws yuav tsum tiaj tus. Qhov yuam kev ntawm qhov siab tsis sib npaug ntawm ob lub cib uas nyob ib sab yuav tsum tsis pub tshaj 3 hli. Lub cib thiab lub cib yuav tsum sib dhos ze ze. Yuav tsum tsis txhob muaj qhov sib nrug lossis xoob.

06Cov kab sib txuas cib feem ntau siv nrog 2.5 hli, 15 hli dav, thiab 2.5 hli. Qhov tob ntawm cov kab sib txuas cib yuav tsum tsis pub tshaj 20 hli. Ntawm 10 qhov chaw kuaj xyuas ib 5m cib, nws yuav tsum tsis pub tshaj 3 cov ntsiab lus ntau tshaj 3 cov ntsiab lus ntau tshaj 3 cov ntsiab lus. Cov kab sib txuas cib yuav tsum tau ntxig thiab nias nrog cov hlau nyias nyias rau cov kab sib txuas cib tshaj 3 hli.

07Cov kev ceev faj rau cov cib ua thaum lub caij ntuj no

①Qhov chaw teeb tsa ntawm cov cib refractory yuav tsum tau tsa thiab npog nrog daim ntaub tiv nag kom tiv thaiv dej khov thiab daus kom tsis txhob ntub.

②Qhov chaw ua haujlwm yuav tsum muaj cov chaw ua cua sov thiab cua sov rwb thaiv tsev, kom qhov kub tsis qis dua +5 ° C. Txawm tias txoj haujlwm lossis hnub so raug tso tseg, tsis pub cuam tshuam cov rwb thaiv tsev. Cov cement refractory raug do nrog dej kub.
